BRACKET- ron ANGULAR-WALLED TUBING.

To all whom it may concern Be it known that I, WILLIAM B..'Fos'rnn,

va citizen of the United States, and a resident of Utica, in the countyof Oneida and State of New York, have invented certain new and usefulImprovements in Brackets for Angular-Walled Tubing; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the reference numerals marked thereon,which form part of this specification.

My present invention relates to brackets for use with square or otherangular-walled tubing. V i

In bedstead and crib construction having square or other angular-walledtubing it is found that a bracket'attached to and bearing simply againstthe flat side of such tubing tends to distort or cave in the flat sideor wall of the tubing opposite the foot of the bracket. This is soespecially where the bracket is subjected to sharp shocks or blows as isthe case where the bracket is used to arrest the downward movement ofthe sliding side of a crib.

It is thepurpose of my invention to provide a bracket which will obviatethe above named disadvantage and which will be simple in constructionand attachment and efiicient and durable in use.

A further-purpose is to provide a bracket of such construction that theshock or pres-- sure transmitted to the bracket will be trans mitted notsimply against the fiat side of the tubing, but against the adjacentangles of the tubing which are well adapted to resist the pressure;

A further purpose is to provide in combination with such a bracket meansfor pre venting the bracket from twisting or becoming displaced upon thetubing when the bracket is fastened by a single bolt or rivet to thetubing.

Figure 1 is an isometric projection of a bracket embodying my inventionas applied to a section of square tubing.

"Fig. 4is a side elevation of the side-of have illustrated the bracketembodying my invention in connection with a section of square tubing 6of which the side 7 is engaged by the bracket. The sides of ,the tubing,namely 8 and 9 adjacent the side 7 form the corners or edges 8 and 9 Thebracket 10 may be varied as to its shelf portion 11 according to thepurpose of the bracket. In the drawings I have illustrated a brackethaving in its shelf portion 11. a longitudinally extending slot 12 toadapt the shelf to be used in a sliding side crib to support theprojecting ends of a sliding side in which construction a guide rodextends downwardly through the slot 12 as a guide for the sliding sideall as well known in that branch of the art so not further describedherein, as it is not material .to my invention.

The bracket has its tube engaging portion 13 extend downward and towardits lower end is extended laterally preferably as shown in the drawingsin both directions sufficiently to form two opposite lower ends thebracket is attached to the tubing in an obvious manner.

It will now be seen that downward pressure or shocks or blows taken uponthe shelf portion 11 of the bracket will be communicated to the tube 6not simply against the middle or intermediate flat portion of the side 7but through the extended lower end or arms 14 of the bracket against theedges 8 and 9 of the tube which obviously are opposite the adjacentwalls 8 and 9 which form angular reinforcements for the edges 8 and 9directly engaged by thearms 14L In this way the tube is protected frombeing bent or distorted even by repeated shocks or with fingers 18projecting from the arm portions 14 past the extreme edges 8 and 9 ofthe side 7 and a short distance around,

onto or opposite the adjacent opposite sides 8 and. 9 of the tube.Itwill now be seen that when a bracket is made of proper size andproportion to fit a given shaped and sized tube 6 these fingers 18 willprevent the bracket from swinging upon the rivet- 17 as a pivot and soaid in locating the bracket when it is being placed upon theshelf-portion, a downwardly-extending tube engaging portion adapted tobear against one flat side of the tubing, said downwardly-.v

extending portion having its lower part eX- 1 tended laterallysufliciently to bear against the opposite edges of the engaged tube sidewhereby the adjacent angles of the tube take the pressure fromthebracket and fingers on said laterally extended parts extending aroundthejsaid adjacent angles of thetnbe.

In witness whereof I have afiixed my signature, this 2d day of June,1920.
